Energy efficient transmit antenna selection scheme for correlation relied beamspace mmWave MIMO system

mmWave communication system that offers high datarate are accompanied by massive number of antennas for high gain transmission. These large array of antennas requires special beamforming schemes and also requires large number of RF chains. Beamspace MIMO is a beamforming architecture that employs large antenna array and supports limited number of RF chains by converting conventional mmWave channel into sparse channel. Multiple antenna array system are susceptible to antenna correlation effect thereby reducing the system capacity. Transmit antenna selection methods considering the effect of antenna correlation provides feasible solution by maximising the system capacity and energy efficiency. In order to improve the energy efficiency of the transmitted signal three new transmit antenna selection schemes are proposed by considering the effects of antenna correlation. The simulation results demonstrate that the proposed methods improve energy efficiency and sum rate.

A review of power system protection and asset management with machine learning techniques

Power system protection and asset management have drawn the attention of researchers for several decades; but they still suffer from unresolved and challenging technical issues. The situation has been recently exacerbated in the wake of the ever-changing landscape of power systems driven by the growing uncertainty and volatility subsequent to the vast renewable energy integration, more frequent natural extreme events due to climate changes, increasing malicious cyberattacks, and more constrained transmission systems as the result of load growth and limited investments. On the opposite side, the proliferation of advanced measuring devices such as phasor measurement units, emerging electric and non-electric sensors, and Internet of Thing (IoT)-enabled data gathering platforms continually expand/nourish the databases; they hence offer unprecedented opportunities to take the advantage of data-driven techniques. Machine learning (ML) as a principal class of artificial intelligence is the perfect match solution to this need and has newly revoked many researchers’ interests to tackle the problems excluding their exact/detailed models. This paper aims to provide an overview on applications of ML techniques in power system protection and asset management. This paper elaborates on issues pertaining to (1) synchronous generators, (2) power transformers, (3) transmission lines, and (4) special and system-integrity protection schemes. In addition to the opportunities offered by the ML techniques, this paper discourses on the barriers and challenges to the wide-spread application of ML techniques in real-world practices.

Where do hamsters go after cereal harvest? A case study.

Agricultural intensification in recent decades has led to a major loss of biodiversity in agricultural landscapes. Special agri-environmental schemes aim at restoring and protecting biodiversity. In Central Europe, the common hamster Cricetus cricetus (Linnaeus, 1758) is a prominent victim of changes in agricultural management and land-use. After cereal-harvest, common hamsters are deprived from shelter and food sources and little is known on how individuals cope with these changes. We investigated how a population of common hamsters use agricultural landscapes after cereal harvest in 45 fields within a distribution hotspot of the common hamster in Central Germany. We recorded hamster burrow densities before and after cereal harvest in the winter cereals as well as in the two most important specialty crops in the study region, red cabbage and carrot. Common hamster burrows were more abundant in cereals than in the specialty crops before harvest. After cereal harvest, common hamster burrow densities decreased in cereal fields and increased in carrot but not red cabbage. Carrot fields thus provide alternative habitat for common hamsters after cereal harvest. Since many carrot cultivars are harvested in late autumn, these fields potentially provide a safe habitat for hamsters until hibernation. We recommend a targeted subsidizing of the cultivation of late harvest carrot cultivars in regions where common hamster conservation is a priority. These fields should be placed strategically and in sufficient quantities in focus landscapes. Other specialty crops could potentially also help in targeted protection schemes but whether and how they can benefit common hamsters after the cereal harvest needs further investigation.

On Solving the Convex Semi-Infinite Minimax Problems via Superlinear 𝒱𝒰 Incremental Bundle Technique with Partial Inexact Oracle

In this paper, we study convex semi-infinite programming involving minimax problems. One of the difficulties in solving these problems is that the maximum type functions are not differentiable. Due to the nonsmooth nature of the problem, we apply the special proximal bundle scheme on the basis of [Formula: see text]-decomposition theory to solve the nonsmooth convex semi-infinite minimax problems. The proposed scheme requires an evaluation within some accuracy for all the components of the objective function. Regarding the incremental method, we only need one component function value and one subgradient which are estimated to update the bundle information and produce the search direction. Under some mild assumptions, we present global convergence and local superlinear convergence of the proposed bundle method. Numerical results of several example problems are reported to show the effectiveness of the new scheme.

FPGA-Based modular multilevel converter (MMC) controller for efficient voltage balancing in real-time simulation

At present, the implementation of the capacitor voltage balancing controller is a great challenge for the real-time simulation of the MMC systems. In this paper, a field-programmable gate array (FPGA)-based MMC controller is presented. In order to break through the bottleneck of sort scheme in real-time simulation, an efficient sorting scheme is proposed. This scheme is integrated by bucket sort and oddeven sort. It can greatly reduce the comparison times and highly leverage the inherent parallelism in FPGA. A special storage scheme is proposed and can greatly reduce resource consumption of sub-module (SM) voltages and make the utilization of FPGA more efficient. This proposed MMC controller is implemented by high-level synthesis (HLS) and a set of optimization methods are proposed to reduce the timestep. The proposed controller offers a controller timestep of 50us on Xilinx VC709 and support for 640 SMs each bridge-arm and 6 bridge-arms in one MMC on a single board. The performance and accuracy are evaluated on a case study of a back-to-back MMC-HVDC system on ADPSS.

The Chasmic Concept of Space Vector Pulse Width Modulation

Many smartly engineered techniques exist when it comes to inverter switching. Every technique holds its specialty, yet this project will focus on the best of them all. Applications of inverters face three major requirements and limitations which are: 1) harmonic contents 2) best utilization of DC-link voltage 3) the switching frequency. Space Vector Pulse Width Modulation technique has undeniable prominence due to the advantages it has over all others. SVPWM is a special switching scheme of the six power semiconductor switches of a three-phase power converter. The popularity of this technique in applications such as control of induction and permanent magnet synchronous motors has baffled the industrial circumference. In this brilliantly established technique, the drawbacks of other prescribed methodologies are improved drastically. SVPWM provides a constant switching frequency and therefore the switching frequency could be easily adjusted. The harmonic generation here is quite less comparatively. Even though SVPWM is more complicated than the preceding techniques, it overshadows all of them. This paper will establish a conceptual premise towards a deeper understanding of this technique.

Використання беззубки звичайної (Anodonta cygnea (Linne, 1758)) як добавки до рибного корму на прикладi африканського сома (Clarias gariepinus (Burchell, 1822))

Purpose. Uzbekistan aquaculture has a huge deficit of balanced feed. In a case of feed production from local ingredients, the problem is the lack of stable source of animal protein. The purpose of this experiment was to find out how swan mussel Anodonta used as a feed additive for African catfish will affect fish growth. Methodology. Minced Anodonta was prepared as follow: mussels were collected from the bottom of ponds after fish harvesting; the collected mussels were kept in the separate aquarium; every day several mussels were taken out, their shells were opened and muscle parts were separated the (mostly mussel leg); then the separated muscle were kept for disinfection in KMnO4 solution of low concentration during 20 min and then crushed to a minced state. Feed was given to African catfish according to a special scheme at the rate of 7% of the fish weight. The control group did not receive the minced mussels and fish were fed with carp feeds.The mixed feed in the experimental group #1 consisted of 50% carp feed and 50% minced mussel. In the experimental group #2, African catfish were fed with minced mussels only. Findings. The experiment showed the clear advantage of feed containing 50% of minced clams and 50% of carp feed. The African catfish fed with this feed significantly overtook fish from the control group in weight because this feed turned out to be either the most balanced in composition or better absorbed by catfish. In the control group, the 100% mixed feed gave an increase of 83.8% in weight and 20.5% in length; in the experimental group #1, the feed (50% mixed feed : 50% minced mussel) gave an increase of 136% in weight and 31.1% in length; at the experiment #2 (100% minced mussel), the feed gave an increase of 95.5% and 20.1% in length. Originality. For the first time the swan mussel was used as a source of animal protein for African catfish.This experiment was conducted for the first time, and it was also found for the first time that the addition of minced swan mussel to the feed of African catfish contributed to a significant weight gain compared to the conventional feed:52.5% more compared to conventional feed and 40.5% more compared to pure minced swan mussel. Practical value. Aquaculturenow is in search of source of animal proteinin connection with growing global deficit of a high quality fishmeal for fish feed production. Use of bivalve mollusks Anodonta, which are also a pest in pond farms, is promising feed for obtaining physiologically determined weight gains. Key words: aquaculture, Africaт catfish (Clarias gariepinus (Burchell, 1822)), feed, animal protein, plant protein, water quality, swan mussel (Anodonta cygnea (Linne, 1758)), weight gain.

A knowledge-based automated design system for mechanical products based on a general knowledge framework

In the field of mechanical product design, there have been difficulties in building a general model to represent a design process since the type of mechanical products is diverse and the design process requires different complex domain knowledge. This results in the need for different domain experts to design special system development schemes for different kinds of mechanical products, which greatly increases the cost of the research and development. In addition, there have been difficulties in the automation, intellectualization and acceleration of mechanical product design process, as the process is based on experiential knowledge and relies extensively on the synthetic decision of experts (SDE), which is hard to be integrated into the design process without the participation of experts in person. To cope with these two issues, a knowledge-based automated design (KAD) system for mechanical products was developed in this study. Firstly, a general feature design flow (GFDF) framework was proposed to represent the design knowledge of various mechanical products from initial design stage, including requirement analysis, to the final automated generation of computer-aided design (CAD) model. Based on parametric technology and application programming interface (API) functions, the GFDF framework decomposes the explicit and implicit knowledge of a top-down design process into four rank-correlated features and two feature correlation matrices (FCMs) respectively. Based on the GFDF framework, a requirement analysis method using analysis hierarchy process (AHP) was proposed to transfer qualitative features to quantitative parameters. Secondly, by adopting the support vector regression (SVR) machine, a feature reuse case adaptation (FR-CA) method based on case-based reasoning (CBR) was proposed to achieve the automation and intellectualization of parameter solving integrating the SDE without the actual participation of experts. The FRCA method transforms the SDE into an FCM, which can be identified during the case adaptation process, and maximizes the utilization of solved features in each adaptation process. A comparison experiment between FR-CA and conventional method for case adaptation indicated that the adaptation performance of FR-CA method is better than that of the conventional one. Finally, the KAD system was applied to the design of corn huskers. The result showed that the KAD system could improve the automated, intelligent and rapid design of mechanical products.

Linear Transient Dynamic Analysis of Plates With and Without Cutout

The present work exhibits the analysis of a plate with and without cutout considering the dynamic analysis in a transient zone with its application in the civil, structural, and aerospace industry. For this, first-order shear deformable C0 continuous Finite Element (FE) is implemented to examine transient response of plate. The governing ODE of motion’s is integrated using central difference explicit time integration scheme. A lumped mass matrix is obtained by a special diagonlization scheme and the total mass of the element is conserved by inducing effective rotary inertia terms. A FE program is developed based on derived FE formulation to investigate the effect of dynamic loading on such plates. The analysis exhibits the results in terms of displacement, forces, and bending moment of the plate for various aspect ratios and different parameters. The results are shown in terms of tables and graphs for smaller to larger cutout in plates with its different aspect ratio considering transient analysis. The results reveal that transient dynamics analysis shows a considerable difference in the behavior of plates with and without cutout in terms of time period, amplitude, and bending moment than that obtained from static analysis.

Give them wings to fly: critiquing the Special Needs Assistant scheme through the lens of pupil independence

ABSTRACT A significant increase in the paraprofessional workforce has occurred internationally, aimed at facilitating inclusive education. Within Ireland, this is evidenced in the SNA scheme for pupils with significant care needs. This paper focuses on the constructs of SNA support and pupil independence, as based on large-scale research across 20 Irish mainstream primary classes. The study was modelled on Strand 2 Wave 1 of the UK’s ‘Deployment and Impact of Support Staff’ project, involving systematic observations and case studies. Following qualitative and quantitative analysis, findings serve to expand the construct of pupil independence beyond adaptive behaviour to include themes of pupil voice and psychological empowerment. The research also highlights both positive and negative educational practices to support pupil independence including SNA rotation, SNA–pupil proximity and prompting. Results are discussed in light of previous national and international research. Future directions of the SNA scheme are presented, including the potential of scaffolding theory to advance applied practices. Limitations of the research are acknowledged, including implications for research, theory, policy and practice. This research presents as the first Irish study to examine the SNA role using systematic observations, serving to extend existing research on the complex relationship between paraprofessional support and pupil independence.

System parameterization of the budget model of investment construction project

This article reviews the definitions of budgeting and budget model, their role in cost management of investment construction projects, and the subject field of budget modeling of a project. The author indicates the relevance of implementation of budgeting in management of investment construction projects, as well as the factors of low efficiency of this process. The subject of this research is the system variables of the budget model: functions, content, structure, levels, quantitative and qualitative indicators, standards, methodological and analytical parameters, and financial modeling processes. The peculiarity of the subject of research lies in systematicity, need for consolidation of budgets in various aspects, and compatibility of the local budget models for creating a reasonably universal system for supporting managerial decision-making. Description is given to the basic methodological provisions of the development of budget models of investment construction projects. This article is first to elaborate on the analytical parameters of budget modeling of investment construction projects, as well indicate various parametric levels in reference to each other. The author develops the financial planning processes and the pattern of project budgeting, as well as adapts the cybernetic principles of “input – output”. It is suggested to use a special accounting scheme in the budget model of the project, which is based on the managerial accounting policy approved by the subject. For achieving compatibility of the methods of financial administration, the author offers to coordinate the cost pool in estimates and budgets, maximal expenditure accounting, reduce scheduling uncertainty, and consider dynamic factors. The budget model is viewed as an input parameter of cost control over the investment construction projects. The vectors of further improvement of budgeting of investment construction projects are proposed.

Multi-alloying of nanomet: conception and implementation of homogeneous nanocrystallization in high-flux density soft magnetic alloys

This study demonstrates how multi-alloying the Fe-Si–B–P–Cu (Nanomet®) can avoid the strict requirements on the annealing scheme in terms of high heating rate and narrow annealing temperature range in order to grow a homogeneous ultrafine nanocrystalline structure. The rather restricted amorphization capability sets a low limit of the maximum thickness of the amorphous precursor. These shortcomings have their origin in the existence of detrimental pre-existing nuclei in the amorphous precursors, which in turn potentially lead to a heterogeneous crystallization. Here, we have multialloyed Nanomet with CoCNi- and CoCMo- to avoid the creation of these pre-existing nuclei. This leads to improved amorphization capability and changes a potentially heterogeneous crystallization to a homogeneous nanocrystallization over a much broader temperature range than for unalloyed Nanomet. Thus, the requirements for the annealing are much relaxed. This work encompasses quenching the amorphous precursors using melt-spinning, investigating the crystallization temperatures by calorimetry, showing the depletion of pre-existing nuclei by magneto-thermo-gravimetry, conceptualizing the crystallization dynamics using isothermal calorimetry, and finally revealing the excellent soft magnetic properties over a broad annealing temperature interval (390–490 °C for the substituted alloys compared to 410–470 °C for unalloyed Nanomet). The multi-elemental substitution of Fe with CoCMo and CoCNi in Nanomet alloy nearly maintains the saturation magnetization and the coercivity. We believe the substituted alloys provide a better alternative to Nanomet with improved amorphization capability and homogeneous nanocrystallization without any special heat treatment scheme.

A Study On The Educational Problems Of Scheduled Caste People With Special Reference To Biswanath Gaon Panchayat

Scheduled Castes are the most disadvantaged socio-economic groups in our India. The Scheduled Caste people are scattered all over the country. They are mainly settled in rural areas and are dependent on the upper castes people for their livelihood. The scheduled caste people are mostly engaged in low paid manual occupations and also work as bonded labours. Majority of the scheduled caste people do not conscious in getting education and also unaware about the value of education for their lives. They do not give priority to send their child in school or colleges. Poverty, illiteracy, poor social environment, lack of general awareness etc. are the problem that scheduled caste people suffer from. The Government of India has special schemes to enable access to opportunities including scholarship for education, various educational facilities, financial support and skill building for setting up their lives, reservation in jobs, reservation for getting education and special courts to address instances of atrocities and violence. Though they have various educational schemes and policies but they unaware their rights and opportunities to upgrade their lives. It is utmost important for us to understand and analyses the problems in the context of their previous conditions which continue to have a bearing on the present. This paper identifies and analyses the educational problems of scheduled caste people in Biswanath Gaon Panchayat.

Generalized shape optimization of transient vibroacoustic problems using cut elements

AbstractThis article propose a generalized shape optimization method for transient coupled acoustic–mechanical interaction problems. The transient problem formulation allows to optimize for a broadband frequency content and the possibility to investigate transient phenomena such as pulse shaping. Throughout the work, the geometry is defined with the help of a nodal‐based design field, for which its zero‐level contour describes the interface between acoustic and structural domains. The approach utilizes a fixed background mesh to represent the geometry and a cut element immersed boundary method for the physical modeling. This modeling approach provides accurate solutions to the strongly coupled governing equations based on a special integration scheme. The optimization problem is solved using a gradient‐based optimizer and employs a fully discrete adjoint approach for calculating the sensitivity information. A numerical examination on the accuracy of the sensitivity analysis compares the fully discrete gradients to the commonly used semidiscrete adjoint approach for transient optimization revealing the importance of consistent sensitivities. The transient design formulation is validated on a 2D benchmark problem concerning the design of a time‐harmonic acoustic partitioner. The developed framework is then applied for the design of vibroacoustic pulse shaping devices to demonstrate control of a transient phenomena.

Reversible Data Hiding Using Hybrid Method of Difference Expansion on Medical Image

Data hiding in the image can cause permanent distortion (irreversible), in other applications such as medical images, distortion can cause misdiagnosis. To overcome these problems, a special scheme is required for the embedding data on medical image. Reversible data hiding is a scheme that can restore the image to original image without distortion after the embedded information is extracted. Difference Expansion (DE) is one of the schemes in reversible data hiding that is simple and easy to implement. In this paper, we propose two schemes based a hybrid combination of DE to increase on capacity and visual quality. Medical image has characteristics is the large of smooth block areas, in which DE method is applied to the non-smooth areas image. We used four different medical images to evaluate the proposed scheme. The results showed that the proposed scheme has a high capacity and better visual quality than the original scheme and similar schemes have been proposed previously. Embedding capacity of the proposed scheme is up to 0.66 bpp with visual quality of PSNR value is up to 48 dB.

Measurement of the difference in the geomagnetic induction between the magnetometer pillars of the geomagnetic observatory of the Ukrainian Antarctic Akademik Vernadsky station

The article describes the features of measurements of spatial inhomogeneities of the geomagnetic field between the pillars of magnetometers in the measuring pavilion, which were carried out at the geomagnetic observatory of the Ukrainian Antarctic Akademik Vernadsky station in 2015. Some preliminary results of these measurements are also given. The concept of the timescaled value of the geomagnetic field induction is introduced, which is convenient for compensating for time changes of the real geomagnetic induction and bringing it to one reference level of induction. The differences in geomagnetic induction between pillars are obtained as the differences in time-scaled values of the geomagnetic induction on the pillars. The technique allows comparing long-term series of measurements of field inhomogeneities at important points in space. The main objectives are to increase the accuracy of measurements of local inhomogeneities of the geomagnetic field in the measuring pavilion of the geomagnetic observatory of the Ukrainian Antarctic Akademik Vernadsky station and to determine the differences in the geomagnetic induction between the pillars on which the magnetometer sensors are installed. Obtaining numerical values of the differences in the geomagnetic induction between the pillars as objective criteria needed to assess the accuracy of the data in the final processing of geomagnetic observatory data. The method of comparison of two series of data is used: one obtained by the scalar magnetometer installed in the observatory as a mandatory stationary device, and the other obtained during measurements with a mobile magnetometer at the desired points in space. Compensation of temporal changes of the geomagnetic field by time-scaling the measurement readings of the mobile magnetometer relative to one reference value and thus, bringing them to one selected and fixed time epoch. Special geometric scheme of mobile measurements in the space around the pillars with magnetometer sensors or at important points in space. A rough estimate of method errors. Based on the analysis of the obtained data, the efficiency of the method and its acceptable potential accuracy were confirmed. We obtained approximate numerical values of the differences in the geomagnetic field induction between the pillars on which the magnetometer sensors are installed. Further increase in the accuracy of determining these differences is possible using modern devices of high accuracy and GPS-synchronization of mobile measurements.
